D-Link DIS-100E-5W [6/16] Connecting the alarm relay

DANGER: Never attempt to view optical connectors that might be emitting laser energy.

Do not power up the laser product without connecting the laser to the optical fiber and

putting the cover in position, as laser outputs will emit infrared laser light at this

point.

Connecting the Power

The switch can be powered using two power supplies (input range 12V – 58V). Insert the positive and

negative wires into the V+ and V- contacts on the terminal block and tighten the wire-clamp screws to

prevent the wires from being loosened.

NOTE: The DC power should be connected to a properly-fused power supply.

Connecting the Alarm Relay

The alarm relay output contacts are in the middle of the DC terminal block connector as shown in the

following figure.

By inserting the wires and setting the DIP switch of the Port Alarm to “ON”, the relay output alarm will detect

any port failures, and form a short circuit.

The alarm relay out is “Normal Open”.
